Essays on Bacteria

Did you know, bacteria are a living and thriving species? “There are over ten million different types of bacteria! They can live within soil, in the ocean, or inside the human gut”. I am very interested in seeing what type of cleanser best kills these...

Bacteria are microscopic single celled organisms that thrive in diverse environments. They can live within soil, in the ocean and inside the human gut. The three basic bacterial shapes are spherical, bacillus and spiral. (Aryal.S,2015) Tuberculosis (TB) is a bacterial infection that spreads through inhaling...

Poverty is one of the world’s recurring and concerning issues which has affected countries, especially third-world countries, and this includes Philippines. During the first half of 2014, 25.8% of the Philippine population suffers from poverty, which decreased to 21.6% in 2015, and was then increased...

Early observations by application of specific strains revealed that virulent pneumococci were surrounded by a structure now recognized as the capsule. The capsule played a central role in the discovery of the ‘transforming principle’ since it was using this genetic trait and this microorganism where...

Production of crude alkaline protease from Bacillus cereus strain S8 (MTCC NO 11901) was carried out by statistically optimized media supplemented with molasses, 1% (w/v); potassium nitrate, 0.75% (w/v); salt solution, 5% (v/v); {MgSO4.7H2O, 0.5% (w/v); KH2PO4, 0.5% (w/v)}; FeSO4.7H2O, 0.01% (w/v) and CaCO3, 0.5%...

A microorganism is a living organism and they can only be seen through a microscope. Bacteria Bacteria cells are prokaryotic cells (single celled organisms). Bacteria cells have a variety of different organelles including a single circular strand of DNA, plasmids (small rings of DNA), a...

Results Isolation of sponge-associated bacteria from 3 different sponges resulted 80 bacterial isolates which are morphologically different. Nine bacterial isolates were obtained from sponge Hyrtios sp., 20 bacteria isolated from Smenospongia sp., and 51 bacteria isolated from Verungola sp. Sponge-associated bacteria with anti-Vibrio spp properties...

There are some bacteria in the environment that are so pervasive and detrimental as the disease process caused by them made it looks like we are getting eaten by an unseen entity typically known as the flesh-eating microbial agents. Among all of the sexually transmitted...

Aim: The present study was undertaken to study the incidence of microbial spectra in gallstone disease and effect of bacteriobilia on wound infection. Introduction: Biliary calculus disease is commonest disorder affecting the gastrointestinal tract and remains the most commonly encountered cause of morbidity. There is...

“ Bad breath is caused by odor-producing bacteria that grow in the mouth. When you don’t brush and floss regularly, bacteria accumulate on the bits of food left in your mouth and between your teeth. The sulfur compounds released by these bacteria make your breath...

Extremophiles are organisms that live in conditions which humans consider “extreme.” “Extreme” environments include but are not limited to extreme pressure, extreme cold, intense heat, highly acidic environments, and highly saline environments. These conditions were once believed to not have the ability to sustain life....

Right through history, from the genus Mentha L. and the family (Lamiaceae), species which includes about 260 genera and more than 7000 species are being used worldwide and one example is Mentha piperita L. (Brahmi, Khodir, Mohamed & Pierre, 2017) commonly known as peppermint a...

Appearance of Antibiotic has greatly improved human health. Bacterial infections were once a leading cause of mortality in the societies, however, antibiotic invention decreased the mortality rate in bacterial infections considerably. Because of the antibiotics, the mortality rate decreased by 8.2% per year from 1900...

“ In 1978, genetically engineered human insulin was produced by utilizing a new technology that would hopefully produce unlimited amount of human insulin by controlling the power of tiny microorganisms. People had used bacteria to enhance their lives from a long time ago. For instance,...

In 2017, the World Health Organization compiled a list of “priority pathogens”, this list included 12 antibiotic-resistant bacteria. Acinetobacter baumannii made the slot for “priority one pathogen for antibiotic research and development. ” A. baumannii infects patients in critical care units, demonstrates multi-drug-resistance and can...

Cyanobacteria are photosynthetic bacteria that share some properties with algae and are found naturally in lakes, streams, ponds, and other surface waters. Cyanobacteria can rapidly multiply in surface water and cause “blooms.” Several types of cyanobacteria, for example Anabaena sp have gas-filled cavities that allow...

Diagnosis of fowl cholera depends on identification of the causative bacterium, P. multocida, following isolation from birds with signs and lesions consistent with this disease. Presumptive diagnosis may be based on the observance of typical signs and lesions and/or on the microscopic demonstration of bacteria...

Bacteria Biology Report Aim: To find the effects that disinfectants have on the kill zone at various concentrations on peppercorn bacteria in an incubated environment. Hypothesis: I believe that as we increase the concentrations of disinfectants the kill zone will increase in diameter. This is...

The discovery of antibiotics is one of the wonders innovations that humanity has experienced, but this light miracle died out just after the appearance of antibiotic resistance and the understanding of these origins and mechanisms. Although some authors have implemented corrective plans to minimize the...

Introduction Ruminants diet is rich in fiber (consists of polymers e.g. cellulose) and low in proteins. Almost all animals as well as mammals lack the enzymes for metabolizing cellulose. Only microorganisms possess such enzymes which aid in fermenting cellulose and other polysaccharides consumed by the...

Physicians are not completely certain that why RA, a disorder where the body works for struggle the joints, however Science is currently paying attention at a possible offender: germs which stays through bowels of us. It has been discovered fascinating connections in bowel germs or...

The Paramecium tetraurelia is an unicellular ciliate that can be found in almost any sample of still water. Paramecium tetraurelia is a widely distributed, free-living unicellular organism that feeds on bacteria and can easily be cultured in the laboratory(Beisson,et al.,1970). Its large size and complex...

Everything humans touch is brimming with billions of microbes. People eat at their desks, they put their bags on dining room tables, and they turn doorknobs that hundreds of other hands have touched. These things are done without a second thought, despite the fact that...

By and large, for Gram-negative microscopic organisms, starved cells are morphologically and physiologically altogether different from log-stage cells. The underlying reaction to carbon-vitality source confinement is to attempt to dodge the stress by expanding expression or scavenging frameworks to have the option to use any...

Viral Disease: Structure: Viral diseases are often associated as not living as they do not move and stay on the outside of a hosts cell. They are made up from strands of nucleic acids, these consist of either DNA or RNA, which are surrounded by...
